Subject: [Qemu-devel] [PATCH v3 0/3] Make KVM/MSI code device-ID-aware
Date: Wed, 14 Oct 2015 15:59:56 +0300 [thread overview]
Message-ID: <cover.1444827228.git.p.fedin@samsung.com> (raw)
On ARM architecture ITS (Interrupt Translation Service), additionally to
normal MSI data, uses also side-band device IDs. This series prepares the
infrastructure to handling them.
This small series is actually an extraction from vITS support RFC
(https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg07074.html).
Nobody reviewed it so far, however some bits of it could actually be
applied early. This series consists only of those parts, which do not
depend on any new unreleased kernel APIs.
v2 => v3:
- Use official "requester ID" denotion everywhere. Renamed getter function and
MemTxAttrs field.
v1 => v2:
- Improved commit messages, more explanations
- msi_device_id() function made architecture-specific
Pavel Fedin (3):
kvm: Make KVM_CAP_SIGNAL_MSI globally available
hw/pci: Introduce msi_requester_id()
kvm: Pass PCI device pointer to MSI routing functions
